Kitec Plumbing: How to Spot It and Why It Matters When You Buy

Kitec is a flexible composite pipe — an aluminum core wrapped in plastic (PEX-AL-PEX) — joined with brass fittings. It was popular in North American residential construction from 1995 to 2007 for both potable water and radiant heating (source: Square One Insurance). Because it was easy to install, you’ll find it in a lot of Toronto-area condos and renovated homes built around that era.

Two things go wrong. First, the brass fittings dezincify: zinc in the brass corrodes when exposed to oxygen and moisture, forming zinc-oxide buildup that restricts flow and weakens the joints. Second, the pipe itself breaks down under heat and pressure (the orange hot-water pipe is certified only to roughly 82°C; source: Square One Insurance). Together they take a system from a slow weep to a sudden burst — and bursts tend to happen when nobody is home, flooding more than just one unit.

How to identify Kitec yourself (three places to look)

• Colour: most often orange for hot, blue for cold. But Kitec was also made in red, grey and black, so colour is a clue, not proof (source: WaterSmart Systems).
• Printing: the hard evidence is the brand name printed on the pipe or stamped on the brass fittings — Kitec, Kitec XPA, PlumbBetter, IPEX AQUA, WarmRite, AmbioComfort, KERR Controls, XPA, Plomberie Améliorée. Fittings may read Kitec or KTC, and pipes may show CSA B137.9/10 or ASTM F1974 (source: WaterSmart Systems).
• Electrical panel: many Kitec homes have a bright yellow or neon sticker on the panel door noting that Kitec was used and the electrical system cannot be grounded to it (source: WaterSmart Systems).

Where to look: near the hot water tank, in the mechanical room, and under kitchen sinks and bathroom vanities where pipes exit the wall. A white or green chalky residue around the brass fittings means the system has already started to degrade.

A Kitec class action was launched across the U.S. and Canada in 2009, and IPEX established a US$125 million settlement fund (approved in 2011) to help pay for replacement. But the deadline to file claims was January 9, 2020, and it has passed — you can no longer claim the cost of replacing Kitec (sources: kitecsettlement.com, Square One Insurance). In other words, if you buy a home with Kitec today, the replacement cost generally falls on you as the owner. That is exactly why it needs to be priced and negotiated in a transaction.

Why it matters for buyers and condo owners

• Insurance: according to Square One Insurance, most homes with Kitec can still be insured if there’s no leak history, but a higher deductible applies to Kitec-related losses — and some insurers decline coverage outright or require replacement first. Kitec is something you must disclose on an application; hiding it can void the policy.
• Resale: Kitec is a known defect with a disclosure obligation. Once a buyer knows, it usually translates into a lower offer or a request that the seller replace it first — it enters the negotiation.
• The shared risk in condos: replacement cost falls on the owner, even in a condo. If only some units in a building are replaced, a burst in an un-replaced unit above can flood yours, and the insurer may deny the claim because the source was Kitec (source: Square One Insurance, local plumbing practice). That’s why a building-wide replacement is the safer path — going it alone is where owners get hurt.

• Before you buy: make “is there Kitec?” a specific item for your home inspector. If it’s there, work the replacement cost into your offer price or into a condition.
• Estimate the cost: Square One Insurance puts replacement at roughly CAD $5,000–$15,000. For GTA condos, local plumbers quote about $5,000–$6,500 for a one-bedroom and $8,000–$10,500 for two-bedroom and larger units, while larger houses can exceed $25,000. Opening and refinishing walls (paint, tile) is usually the biggest line item.
• If you already own: tell your insurer and confirm your coverage terms; if you’re in a condo, push the board to evaluate a building-wide replacement — it’s cheaper and safer than each owner doing their own.
• Use a licensed plumber: replacement means opening walls, re-piping and testing. Hire a licensed, experienced contractor and keep the documentation — it helps with both disclosure and insurance.

Q: How can I quickly tell if a home has Kitec plumbing?

Check three things: pipe colour (most commonly bright orange for hot and blue for cold, though Kitec was also made in red, grey and black), the printing on the pipe or brass fittings (Kitec or KTC, brand names like PlumbBetter, IPEX AQUA, WarmRite or AmbioComfort, and codes such as CSA B137.9/10 or ASTM F1974), and a warning sticker on the electrical panel. The easiest places to look are near the hot water tank, in the mechanical room, and under kitchen sinks and bathroom vanities where pipes exit the wall.

Q: Can I still claim money from the Kitec class-action settlement?

No. IPEX established a US$125 million settlement fund (approved in 2011), but the deadline to file claims was January 9, 2020. After that date you can no longer claim the cost of replacing Kitec. Today the replacement cost generally falls on the property owner. Sources: kitecsettlement.com, Square One Insurance.

Q: Will Kitec affect my insurance or the home’s resale?

Often yes. According to Square One Insurance, most homes with Kitec can still be insured if there is no history of leaking, but a higher deductible applies to Kitec-related losses, and some insurers may decline coverage or require replacement first. Kitec is also a known defect that must be disclosed on resale, so it typically shows up in buyer offers and negotiations.

Q: How much does it cost to replace Kitec?

It varies by property. Square One Insurance estimates replacement at roughly CAD $5,000–$15,000. For GTA condos, local plumbers quote about $5,000–$6,500 for a one-bedroom and $8,000–$10,500 for two-bedroom and larger units, while larger houses can exceed $25,000. Opening and repairing walls (drywall, paint, tile) is usually the biggest cost driver.
